I'm trying to upload a pdf file then I need to parse it using pdf2json without saving the file in the directory but pdf2json requests a directory path in loadPDF. any idea what can I do, please?

https://www.npmjs.com/package/pdf2json

@Post('getFields')
      @UseInterceptors(AzureStorageFileInterceptor('file'))
        @UploadedFile() file?: UploadedFileMetadata){
  
        if (!file || Object.keys(file).length === 0 ||file.constructor !== Object) {
            throw UtilError.createErrorError('Missing file.');
        }
        const pdfParser = new PDFParser(file);
        pdfParser.on("pdfParser_dataError", errData => console.error(errData.parserError) );
        pdfParser.on("pdfParser_dataReady", pdfData => {
            fs.writeFile(path.join(__dirname, './../../../../src/entities/skiplino/form/F1040EZ.json'), JSON.stringify(pdfData), function(){ console.log("done!") }
            );
        });
         return await pdfParser.loadPDF(./../file);
    }
